M1911是一把由約翰·勃朗寧設計、裝填.45 ACP子彈的單動式擊發半自動手槍。在1911年到1985年間作爲標準配置被美國軍警攜帶,直到現在仍有一些部門裝配此手槍。其在第一次世界大戰第二次世界大戰韓戰越戰中都被廣泛應用。在1940年,1911年設計的M1911的正式名稱是.45口徑自動手槍 M1911(Automatic Pistol, Caliber .45, M1911)、1924年設計的M1911A1的正式名稱是.45口徑自動手槍 M1911A1(Automatic Pistol, Caliber .45, M1911A1),到了越戰時期則改稱.45口徑手槍 自動 M1911A1(Pistol, Caliber .45, Automatic, M1911A1)。在整個服役期間美國共生產了270萬支M1911及M1911A1手槍。

M1911可說是勃朗寧使用短後座力原理的設計中最爲人知的一支手槍。其影響力不止使其本身設計被廣泛流傳,這種驅動系統也被推上20世紀、甚至近代武器設計的高峰。

歷史

發跡

The M1911 pistol originated in the late 1890s, as a search for a suitable self-loading (or semi-automatic) handgun, to replace the variety of revolvers then in service. The United States of America was adopting new firearms at a phenomenal rate; several new handguns and two all-new service rifles (the M1892/96/98 Krag and M1895 Navy Lee), as well as a series of revolvers by Colt and Smith & Wesson for the Army and Navy were adopted just in that decade. The next decade would see a similar pace, including the adoption of several more revolvers and an intensive search for a self-loading pistol that would culminate in official adoption of the M1911 after the turn of the decade.

Hiram S. Maxim had designed a self-loading pistol in the 1880s, but was preoccupied with machine guns. Nevertheless, the application of his principle of using bullet energy to reload led to several self-loading pistols in the 1890s. The designs caught the attention of various militaries, each of which began programs to find a suitable one for their forces. In the U.S., such a program would lead to a formal test at the turn of the 19th to the 20th century.

During the end of 1899 and start of 1900, a test of self-loading pistols was conducted, which included entries from Mauser (the C96 "Broomhandle"), Mannlicher (the Steyr Mannlicher M1894), and Colt (the Colt M1900).

This led to a purchase of 1,000 DWM Luger pistols, chambered in 7.65 mm Luger, a bottlenecked cartridge. These would go on field trials but ran into some issues, especially in regard to stopping power. Other governments had also made similar complaints, which resulted in DWM producing an enlarged version of the round, the 9mm Parabellum (known in current military parlance as the 9x19mm NATO), a necked-up version of the 7.65 mm round. Fifty of these were tested as well by the U.S. Army in 1903.

General William Crozier became Chief of Ordnance of the Army in 1901.

In response to problems encountered by American units fighting Moro guerrillas during the Philippine-American War, the then-standard .38 Long Colt revolver was found to be unsuitable for the rigors of jungle warfare, particularly in terms of stopping power, as the Moros had very high battle morale and frequently used drugs to inhibit the sensation of pain.模板:Fact The U.S. Army briefly reverted to using the M1873 single-action revolver in .45 Colt caliber, which had been standard during the last decades of the 19th century; the slower, heavier bullet was found to be more effective against charging tribesmen. The problems with the .38 Long Colt led to the Army shipping new single action .45 Colt revolvers to the Philippines in 1902. It also prompted the then-Chief of Ordnance, General William Crozier, to authorize further testing for a new service pistol.

Following the 1904 Thompson-LaGarde pistol round effectiveness tests, Colonel John T. Thompson stated that the new pistol "should not be of less than .45 caliber" and would preferably be semi-automatic in operation. This led to the 1906 trials of pistols from six firearms manufacturing companies (namely, Colt, Bergmann, Deutsche Waffen und Munitionsfabriken (DWM), Savage Arms Company, Knoble, Webley, and White-Merril).

六件設計提交之後,其中三件很快就被排除,留下了薩維奇、柯爾特和DWM三家的設計進入.45ACP(Automatic Colt Pistol,柯爾特自動手槍)試驗的決賽。雖然三家都還有需要改進的地方,但只有柯爾特和薩維奇重新遞交了改進的設計稿。這曾引發人們對DWM爲何沒有動作的討論,部分人認爲DWM遭受偏見並成爲另外兩家的戴罪羔羊[1],但這個理由與1900年代DWM被採購量高於柯爾特的事實不符。不管理由爲何,1907年到1911年間的試驗就圍繞在要從柯爾特及薩維奇的設計中選出最終作品。這段期間兩家公司都在改進他們的產品,柯爾特經過M1907及M1909之後在1910年研發出了M1910這支可靠的手槍。在最後的6,000發射擊測試中,柯爾特的設計以零故障打敗了有37次失靈的薩維奇設計。

在試驗中取得成功之後,這把柯爾特手槍在1911年3月29日正式被軍隊採用,也是其名稱——M1911(Model of 1911、1911型)的由來。到了1913年美國海軍美國海軍陸戰隊也開始裝配這支手槍。而本來只由柯爾特公司生産的M1911,在第一次世界大戰時期也因爲需求過盛開始在政府旗下的春田兵工廠生産。

從一戰戰場上取得的經驗造就了M1911的進步,1924年完成設計並在1926年投入生産的新版本被稱爲M1911A1。 Changes to the original design were minor and consisted of a shorter trigger, cutouts in the frame behind the trigger, a curved mainspring housing, a longer grip safety spur (to prevent hammer bite), a wider front sight, a shorter spur on the hammer, and simplified grip checkering.對此設計不夠熟悉是無法輕易分辨兩個版本的區別。M1911A1也沒有重大的内部改變,兩個版本間的許多零件也可以互換。

第二次世界大戰

第二次世界大戰期間對M1911有極大的需求,戰中約有190萬支被美軍製造並編制給各領域的軍人。其生産權被下放給幾家供應商:Remington Rand (90萬支)、柯爾特(40萬支)、Ithaca Gun Company(40萬支)、Union Switch & Signal(5萬支)、Singer(500支)、Springfield Armory及Rock Island Arsenal。但在1945年後,政府停止了製造新槍的訂單,而在必要時也傾向使用翻修的舊槍。這把手槍卻仍是許多軍事人員的最愛。[2]

二戰前有少數的柯爾特槍支授權給挪威武器工廠Kongsberg Vaapenfabrikk (這些槍被稱爲"Kongsberg Colt")。 During the German occupation of Norway the production continued.這批手槍在現代收藏者之間非常熱門。德軍仿造了M1911A1並命名為660(a)手槍(Pistole 660(a))。[3]而1911模型也被當作Argentine Ballester-Molina、certain Spanish Star甚至1922年出身的Llama手槍的設計基礎。

Replacement for most uses

二戰後,M1911還是被當作美軍在韓戰越戰甚至沙漠風暴行動中部分單位的主要隨身武器。並持續在伊拉克自由行動持久自由軍事行動中被美軍特種部隊使用。

However, by the late 1970s the M1911A1 was acknowledged to be showing its age. Under political pressure from NATO to conform to the NATO-standard pistol cartridge, the US Air Force's Joint Service Small Arms Program was run to select a new semi-automatic pistol using the NATO-standard 9mm Parabellum pistol cartridge (a cartridge that had been previously tested by the US Army in 1903 and found wanting). After trials, the Beretta 92S-1 was chosen. This result was contested by the Army which subsequently ran its own competition (the XM9 trials) in 1981 which eventually lead to the official adoption of the Beretta 92F on January 14, 1985. By the later 1980s production was ramping up despite a controversial XM9 retrial and a separate XM10 reconfirmation, which was boycotted by some entrants of the original trials, cracks in the frames of the Beretta-produced pistols, and also despite a dangerous problem with slide separation that resulted in injuries to some US Navy service members. This last resulted in it being updated to the 92FS standard, which includes additional protection for the user.

90年代初期大多數的M1911A1被M9手槍取代。 though a limited number remain in use by special units. The United States Marine Corps in particular were noted for continuing the use of M1911 pistols for selected personnel in MEU(SOC) and reconnaissance units (though the USMC also purchased over 50,000 M9 handguns). For its part, the United States Special Operations Command (USSOCOM) issued a requirement for a .45 ACP handgun (Offensive Handgun Weapon System (OHWS) trials). This resulted in the Heckler & Koch OHWS becoming the MK23 Mod 0 Offensive Handgun Weapon System (beating a Colt OHWS, a much modified 1911). Dissatisfaction with the Beretta M9's stopping power has actually promoted re-adoption of the 1911 (along with other handguns) among USSOCOM units in recent years, though the M9 remains predominant both within SOCOM and in the US military in general.

The M1911A1 design is favored by a large number of police SWAT teams throughout the United States. Many military and law enforcement organizations in the United States and many other countries continue to use (often modified) M1911A1 pistols because they favor the greater stopping power of the .45 cartridge and the superior shootability of the weapon.模板:Fact Marine Force Recon, Los Angeles Police Department Special Weapons and Tactics, the FBI Hostage Rescue Team and 1st Special Forces Operational Detachment - Delta (Delta Force) are among them. The Tacoma, WA Police Department made history in 2001 by becoming the first metropolitan police department in nearly 50 years to adopt the 1911 as its official carry weapon. The Tacoma Police Department selected the Kimber Pro Carry II or Pro Carry II HD as optional, department supplied weapons available to its officers.[4]

The M1911A1 is also extremely popular among the general public in the United States for practical and recreational purposes. The pistol is commonly used for concealed carry (thanks in part to a single-stack magazine, which makes for a thinner pistol; thus easier to conceal), personal defense, target shooting, and competition. Numerous aftermarket accessories allow users to customize the pistol to their liking. There are a growing number of manufacturers of 1911-type pistols and the model continues to be quite popular for its reliability, simplicity, and patriotic appeal. Various tactical, target, and compact models are available. Price ranges from a low end of $250 for an imported model to more than $3,000 for the best competition or tactical models such as those by Smith and Wesson, Rock River Arms, Springfield Armory, STI International Inc, Strayer Voigt Inc, U.S. Fire Arms Manufacturing Company,[5] Kimber Manufacturing, Wilson Combat, and Les Baer.

Due to an increased demand for M1911 pistols among Army Spec Ops units, who are known to field a variety of 1911 pistols, the Army Marksmanship Unit began looking to develop a new generation of M1911s and launched the M1911-A2 project in late 2004. The goal was to produce a minimum of seven variants with various sights, internal and external extractors, flat and arched mainspring housings, integral and add-on magazine wells, a variety of finishes and other options, with the idea of providing the end-user a selection from which to select the features that best fit their missions. The AMU performed a well received demonstration of the first group of pistols to the Marine Corps at Quantico and various Spec Ops units and Ft. Bragg and other locations. The project provided a feasibility study with insight into future projects. Models were loaned to various Spec Ops units, the results of which are classified. An RFP was issued for a Joint Combat Pistol but it was ultimately canceled. Currently units are experimenting with a 1911 platform in .40 which will incorporate lessons learned from the 1911 A2 project. Ultimately, the 1911 A2 project provided a test bed for improving existing 1911s. Perhaps we will see development of an improved 1911 variant in the near future.[6]

The Springfield Custom Professional Model 1911A1 pistol is produced under contract by Springfield Armory for the FBI regional SWAT teams and the Hostage Rescue Team. This pistol is made in batches on a regular basis by the Springfield Custom Shop, and a few examples from most runs are made available for sale to the general public at a selling price of approximately US$2,500 each.

Marine Expeditionary Units formerly issued M1911s to Force Recon units.模板:Fact Hand-selected Colt M1911A1 frames were gutted, deburred, and prepared for additional use by the USMC Precision Weapon Section (PWS) at Marine Corps Base Quantico. They were then assembled with after-market grip safeties, ambidextrous thumb safeties, triggers, improved high-visibility sights, accurized barrels, grips, and improved Wilson magazines. These hand-made pistols were tuned to specifications and preferences of end users.

In the late 1980s, Marine Corps Colonel Robert Young laid out a series of specifications and improvements to make Browning's design ready for 21st century combat, many of which have been included in MEU(SOC) pistol designs. However, as the U.S. Marine Corps began its process of hand selecting members from its Force Recon to be submitted to USSOCOM as Marine Corps Special Operations Command, Detachment One (MCSOCOM Det-1), the selection of a .45 ACP M1911A1-based pistol meant roughly 150 units would be needed, quickly. The PWS was already backlogged with producing DMRs, USMC SAM-Rs, and updating M40A1s to M40A3s, so Det-1 began the search for COTS (commercial off-the-shelf) surrogates to use. Discovering that the Los Angeles Police Department was pleased with their special Kimber M1911 pistols, a single source request was issued to Kimber for just such a pistol despite the imminent release of their TLE/RLII models. Kimber shortly began producing a limited number of what would be later termed the Interim Close Quarters Battle pistol (ICQB). Maintaining the simple recoil assembly, 5-inch barrel (though using a stainless steel match grade barrel), and internal extractor, the ICQB is not much different from Browning's original design.

The final units as issued to MCSOCOM Det-1 are the Kimber ICQBs with Surefire IMPL (Integrated Military Pistol Light), Dawson Precision Rails, Tritium Novak LoMount sights, Gemtech TRL Tactical Retention Lanyards, modified Safariland 6004 holsters, and Wilson Combat '47D' 8 round magazines. They have reportedly been used with over 15,000 rounds apiece.

Numbers of Colt 1911s were used by the Royal Navy as sidearms during World War I in .455 Webley Automatic caliber. The handguns were then transferred to the Royal Air Force where they saw use in limited numbers up until the end of World War II as sidearms for air crew in event of bailing out in enemy territory. Some units of the South Korean Air Force still use these original batches as officers' sidearms(2008).

Norway used the Kongsberg Colt which was a license produced variant and is recognized by the unique slide catch. Many Spanish firearms manufacturers produced the M1911 such as the STAR Model P, the ASTAR 1911PL, just to name a few.[7] which eventually led to production of the cheaper Ballester-Molina.

The Brazilian company IMBEL (Indústria de Material Bélico do Brasil) still produces the .45 in several variants for military and law enforcement uses.

The Greek Hellenic Army issues the M1911 as a sidearm. These are WWII production American pistols supplied as military aid in 1946 and afterward as the US aided Greece against Communist expansion.[8]

The Royal Thai Army still uses USGI 1911's that were supplied as military aid during the Vietnam War era.

A Chinese company Norinco exports a clone of the 1911A1 for civilian purchase. Importation into the US was blocked by new trade rules in 1993.

設計

Asking for a .45-caliber automatic pistol was a tall order that few manufacturers or inventors attempted successfully in the early 20th century. To accomplish this, Browning settled on a design that is so timeless, it has been changed little in nearly 100 years of production. The basic principle of the pistol is recoil operation. As the expanding combustion gases force the bullet down the barrel, they give reverse momentum to the slide and barrel which are locked together during this portion of the firing cycle. After the bullet has left the barrel, the slide and barrel continue rearward a short distance.

At this point, a link pivots the barrel down, out of locking recesses in the slide, and brings the barrel to a stop. As the slide continues rearward, a claw extractor pulls the spent casing from the firing chamber and an ejector strikes the rear of the case pivoting it out and away from the pistol. The slide stops and is then propelled forward by a spring to strip a fresh cartridge from the magazine and feed it into the firing chamber. At the forward end of its travel, the slide locks into the barrel and is ready to fire again.

The military mandated a grip safety and a manual safety. A grip safety, sear disconnect, slide stop, half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911A1s. Several companies have developed a firing pin block safety. Colt's 80 series uses a trigger operated one and several other manufacturers use a Swartz firing-pin safety, which is operated by the grip safety.模板:Fact

The same basic design has also been offered commercially and has been used by other militaries. In addition to the .45 ACP (Automatic Colt Pistol), models chambered for .38 Super, 9mm Parabellum, .400 Corbon, and other cartridges were also offered. The M1911 was developed from earlier Colt designs firing rounds such as .38 ACP. The design beat out many other contenders during the government's selection period, during the late 1890s and 1900s, up to the pistol's adoption. The M1911 officially replaced a range of revolvers and pistols across branches of the U.S. armed forces, though a number of other designs have seen use in certain niches.

Despite being challenged by newer and lighter weight pistol designs in .45 caliber, such as the Glock 21, the SIG Sauer P220 and the Heckler & Koch Mk 23, the 1911 shows no signs of decreasing popularity, and continues to be widely present in various competitive matches, such as those of IDPA and IPSC.

  • Capacity: 7+1 rounds (7 in standard-capacity magazine +1 in firing chamber); 8+1 in aftermarket standard-size magazine; 9+ in extended and hi-cap magazines/frames guns chambered in .38 Super and 9 mm have a 9+1 capacity. Some models using double-stacked magazines, such as those from Para Ordnance, Strayer Voigt Inc and STI International Inc have significantly larger capacities. Colt makes their own 8 round magazines which they include with their Series 80 XSE models.
  • Safeties: A grip safety, sear disconnect, slide stop, a half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911(A1)s. Several companies have developed a firing pin block. Colt's 80 series uses a trigger operated one and several other manufacturers (such as Smith & Wesson) use one operated by the grip safety.
  • Grip safety deactivation: A problem for some shooters is that they have trouble deactivating the grip safety when they hold the gun. This primarily affects shooters who have small hands. It can also occur when a shooter places his thumb on top of the thumb safety, which tends to reduce pressure on the grip safety. To rectify this problem, a number of grip safety manufacturers have designed safeties with extended ridges, so that when a shooter grips the gun, his hand will come into contact with the ridges and deactivate the safety (i.e., allowing the gun to fire). Some instructors find this "problem" to be a result of poor hand placement, since an 11 year-old was documented able to do so[9], or worn safety components, known to both military[10] and civilian armorers[11] and systematic checks are to be made to verify its functionality.
